What is the difference between global warming and climate change?
Although people tend to use these terms interchangeably, global warming is just one aspect of climate change. “Global warming” refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere. “Climate change” refers to the increasing changes in the measures of climate over a long period of time – including precipitation, temperature, and wind patterns.

Future Temperature and Soil Moisture May Alter Location of Agricultural Regions
Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.
Changes in Rainfall, Temperature Expected to Transform Coastal Wetlands This Century
Changes in rainfall and temperature are predicted to transform wetlands in the Gulf of Mexico and around the world within the century, a new study from the USGS and the University of Texas Rio Grande Valley concludes.
Walrus Sea-Ice Habitats Melting Away
Habitat for the Pacific walrus in the Chukchi Sea is disappearing from beneath them as the warming climate melts away Arctic sea ice in the spring, forcing the large mammals to “haul out” of the ocean and temporarily live on land.
Old Growth May Help Protect Northwest Birds from Warming Temperatures
Researchers are working to understand how to lessen the impacts of climate change on birds and other forest inhabitants.
Ancient Permafrost Quickly Transforms to Carbon Dioxide upon Thaw
Researchers from the U.S. Geological Survey and key academic partners have quantified how rapidly ancient permafrost decomposes upon thawing and how much carbon dioxide is produced in the process.
Scientists Predict Gradual, Prolonged Permafrost Greenhouse Gas Emissions
A new scientific synthesis suggests a gradual, prolonged release of greenhouse gases from permafrost soils in Arctic and sub-Arctic regions, which may afford society more time to adapt to environmental changes, say scientists in a paper published in Nature today.
Rare Insect Found Only in Glacier National Park Imperiled by Melting Glaciers
The persistence of an already rare aquatic insect, the western glacier stonefly, is being imperiled by the loss of glaciers and increased stream temperatures due to climate warming in mountain ecosystems, according to a new study released in Freshwater Science.
New Heights of Global Topographic Data Will Aid Climate Change Research
The U.S. Geological Survey announced today that improved global topographic (elevation) data are now publicly available for North and South America, Pacific Islands, and northern Europe. Similar data for most of Africa were previously released by USGS in September.
Not-So-Permanent Permafrost
MENLO PARK, Calif. — As much as 44 billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost, or frozen ground, could be released into the environment as the region begins to thaw over the next century as a result of a warmer planet according to a new study led by the U.S. Geological Survey.
Earlier Snowmelt in Colorado Linked to Warmer Air Temperatures and Decreasing Snowfall
Snow in the Colorado mountains is melting significantly earlier in the year, and the changes appear to be related to recent climate trends.

Polar Bear Research, B-Roll 1
Spring 2014. USGS scientists conduct a health evaluation of a young male polar bear in the Arctic as part of the annual southern Beaufort Sea population survey. The bear is sedated for approximately an hour while the team records a variety of measurements and collects key biological samples. The annual population survey has been conducted since the mid-1980's and helps

Collapse-scar bogs formed following permafrost thaw
When permafrost thaws, the ground surface subsides and becomes inundated and the black spruce forest growing on the permafrost can no longer survive. Trees teetering and falling over in thawing permafrost are often referred to as "drunken trees." The black spruce forest is replaced by a saturated bog, dominated by sedges and mosses. This wholesale ecological transformation

Summer ice retreat in the Chukchi Sea between Alaska and Russia is a significant climate change impact affecting Pacific Walruses, which are being considered for listing as a threatened species. This twelve minute video follows walruses in their summer sea ice habitat and shows how USGS biologists use satellite radio tags to track their movements and behavior. The

USGS Public Lecture Series: Climate Change 101
Climate change is an issue of increasing public concern because of its potential effects on land, water, and biological resources. In the next several years, the United States will be challenged to make management and policy decisions as well as develop adaptation and mitigation strategies that will require anticipating the effects of a changing climate and its impacts on
The Cold Facts About Melting Glaciers
Most glaciers in Washington and Alaska are dramatically shrinking in response to a warming climate.
USGS scientist Edward Josberger discusses research from the past 50 years to measure changes in the mass (length and thickness) of three glaciers in Alaska and Washington. These are the longest such records in North America and among the longest in the world.
